Could you please review the patch available at https://lore.kernel.org/linux-riscv/20210629134018.62859-1-xypron.glpk@gmx.de/ The patch is necessary to boot on QEMU with GRUB with large initrd.

Requiring that initrd is loaded below RAM start + 256 MiB led to failure to boot SUSE Linux with GRUB on QEMU, cf. https://lists.gnu.org/archive/html/grub-devel/2021-06/msg00037.html Remove the constraint.
